Abstract

A surgical operating apparatus includes a sheath having a distal end portion and a proximal end portion; a shaft-shaped probe body which is inserted in the sheath and has a distal end portion and a proximal end portion, and in which ultrasonic vibration is transmitted; a jaw which is rotatably supported on the distal end portion of the sheath and has a first electrode section which is one of bipolar electrodes; a probe distal end portion which is provided at the distal end portion of the probe body, is engaged with the jaw, and constitutes a second electrode section which is the other of the bipolar electrodes; and a driving member including a tubular body section, which is inserted in the sheath slidably in an axial direction of the sheath, and an operation section which is provided on a distal end side of the body section and has a connection section for connection to the jaw, the driving member rotating the jaw by a sliding operation of the body section, wherein a tube body of the body section has, on an inner peripheral surface side thereof, an insulation tube which effects electrical insulation between the probe body and the body section, and the insulation tube has a projection portion which projects forward of the body section.

Claims

1. A surgical operating apparatus comprising:

a sheath having a distal end portion and a proximal end portion;

a shaft-shaped probe body which is inserted in the sheath and has a distal end portion and a proximal end portion, and in which ultrasonic vibration is transmitted;

a jaw which is rotatably supported on the distal end portion of the sheath and has a first electrode section which is one of bipolar electrodes;

a probe distal end portion which is provided at the distal end portion of the probe body, is engaged with the jaw, and constitutes a second electrode section which is the other of the bipolar electrodes; and

a driving member including a tubular body section, which is inserted in the sheath slidably in an axial direction of the sheath, and an operation section which is provided on a distal end side of the body section and has a connection section for connection to the jaw, the driving member rotating the jaw by a sliding operation of the body section,

wherein a tube body of the body section has, on an inner peripheral surface side thereof, an insulation tube which effects electrical insulation between the probe body and the body section, and

the insulation tube has a projection portion which projects forward of the body section.

2. The surgical operating apparatus according to claim 1, wherein the operation section includes a U-shaped extension portion with a U-shaped cross section at a distal end portion of a tubular body of the body section,

the U-shaped extension portion includes two opposed side surfaces and a connecting surface which connects the two side surfaces,

the connecting surface has an inclined surface with a distance between the two side surfaces which gradually decreases to a distal end side, and

the connection section is formed on each of the two side surfaces which are disposed at a distal end portion of the connecting surface.

3. The surgical operating apparatus according to claim 2, wherein the projection portion of the insulation tube has an extension portion which extends to an inside of a proximal end portion of the U-shaped extension portion, and

the extension portion prevents the probe distal end portion from coming in contact with an end face of the body section when the jaw is engaged with the probe distal end portion side.
